small fix props in RadioGroup

[DaveMaks]

Hi everyone!

skeleton/packages/skeleton/src/lib/components/Radio/RadioGroup.svelte

Line 52 in 9344fd6

$: classesBase = `${cBase} ${display} ${flexDirection} ${gap} ${background} ${border} ${rounded} ${$$props.class ?? ''}`;

I think it is necessary to correct this line and replace ${cBase} with ${padding?padding:cBase}, because padding is not used anywhere

@DaveMaks so padding isn't used in this (the parent) component. It's passed down to the children components via the Context API. The benefit of setting this on the parent was so it can be done once and match for all children.
